Web2. Electric field from each of these point-like charges ΔQ will be determined. 3. The net field will be found by summing the fields of all the point-like charges ΔQ, forming a Riemann sum. 4. By taking the limit as the number of point-like charges ΔQ increases to infinity, the Riemann sum will converge to a definite integral. 5. WebExample 1.4. 1. A dipole is a distance r from an infinitely-long line of negative charge of density λ. The dipole moment p → is parallel to the line of charge. Find the magnitude of the torque on the dipole in terms of r, p →, and λ. The dipole moment is now pointing directly at the line of charge (perpendicular to it).
